I gave half of the Warwick Physics Colloquium about Arthur Ashkin's Nobel Prize on optical tweezers. The slides are available as Powerpoint (5 MB file) or pdf (2 MB).

We took our diamond magnetometer to the Quantum Technology Showcase in Westminster in November 2018.

We took our new diamond magnetometer to the 2017 Quantum Technology Showcase in Westminster. It is 1,000 times more sensitive than the one we took in 2016 and 1,000,000 times more sensitive than the one we took to the 2015 Showcase.

In July 2016 we showed off our diamond magnetometer at the Royal Society Summer Science Exhibition. The diamond fluoresces red when we shine in green light because of the nitrogen-vacancy centres inside. This video shows the optically-detected magnetic resonance spectrum changing as a magnet is moved away from the diamond.

I featured in the Royal Society ‘Parent-Carer-Scientist’ website and book in 2016.

I created a science activity called ELI5 for over 100 children aged 4-7, and ran it with help from over 30 of their dads, at my daughter's school.

My invited talk at the Bristol Quantum Information Technology (BQIT) meeting on 26th Feb 2014 was titled "Review of State-of-the-Art in Hardware (Solid-State)" and the slides are here as a 14 MB download (CC-by-SA).
